The word "听到" is formed by combining the character 听 (tīng), which means "to hear" or "to listen", with the character 到 (dào), which fundamentally means "to arrive" or "to reach". In this construction, 到 does not signify a physical destination but instead acts as a resultative complement, attaching itself to the action verb to indicate that the action has been successfully achieved or has come to a perceptible result. Thus, 听到 literally conveys the idea of "listening" reaching the point of "arrival", creating the combined meaning of "to have heard" or "to succeed in hearing something".
